EXECUTIVE COMPENSATION (continued) Long-Term Incentive Plan Awards Table - ------------------------------------- Effective January 1, 2003, Owens Corning adopted a Long Term Incentive Plan applicable to certain key employees selected by the Compensation Committee in an effort to more effectively drive long-term business results. The plan is intended to create a strong link between compensation and predetermined business goals designed to increase the value of the Company over a longer horizon and better align executive interests with those of the Company's stakeholders. The plan envisions three-year performance cycles with payouts under the plan dependent upon corporate performance against long term performance goals set by the Committee for each cycle. A new three-year cycle commenced January 1, 2004 and will conclude on December 31, 2006, with payouts, if any, in early 2007. Information concerning the awards for this cycle to the Named Executive Officers is set forth in the table below. Long Term Incentive Plan - Three-Year Cycle Awards in 2004 Estimated Future Payouts under Non-Stock Price-Based Plans (1) ----------------------------------------- Number of Shares, Performance or Other Units or Other Period Until Maturation Threshold Target Maximum Name Rights (#) or Payout ($) ($) ($) - ---- ---------- --------- --- --- --- David T.

High 0 1/1/04-12/31/06 0 438,750 877,500 (1) Each award shown represents the opportunity to earn the amount shown in the "maximum" column of the table if certain "maximum" performance goals established by the Compensation Committee at the beginning of the performance period are attained or exceeded during the performance period. In the event these "maximum" performance goals are not attained, then the Named Executive Officers may earn the amounts shown in the "target" column if the "target" levels of performance are attained, or the amounts shown in the "threshold" column if the "threshold" levels of performance are attained. Participants will earn intermediate amounts for performance between the maximum and target levels, or between the target and threshold levels, and will earn no amounts for performance below the threshold level. The estimates of potential future payouts displayed in the table are based on current salaries; actual payouts, if any, will be based on average annualized salaries over the three-year performance cycle. The performance goals for this three-year cycle are based on the Company's return on net assets. In addition to the three-year performance cycle award, the Committee also established a one-year transition performance period cycle for 2004 in connection with phase-in of the new plan. Payouts pursuant to this performance cycle are reflected in the Summary Compensation Table above. -57- ITEM 11. EXECUTIVE COMPENSATION (continued) Retirement Benefits - ------------------- Owens Corning maintains a tax-qualified Cash Balance Plan covering certain of its salaried and hourly employees in the United States, including each of the Named Executive Officers, in replacement of the qualified Salaried Employees' Retirement Plan maintained prior to 1996 ("Prior Plan"), which provided retirement benefits primarily on the basis of age at retirement, years of service and average earnings from the highest three consecutive years of service. In addition, Owens Corning has a non-qualified Executive Supplemental Benefit Plan ("ESBP") to pay eligible employees leaving the Company the difference between the benefits payable under Owens Corning's tax-qualified retirement plan and those benefits which would have been payable except for limitations imposed by the Internal Revenue Code. Named Executive Officers are eligible to participate in both the Cash Balance Plan and the ESBP. Cash Balance Plan - Under the Cash Balance Plan, each covered employee's earned retirement benefit under the Prior Plan (including the ESBP) was converted to an opening cash balance. Each year, eligible employees earn a benefit based on a percentage of such employee's covered pay. Prior to July 1, 2003, the percentage was 2% for covered pay up to 50% of the Social Security Taxable Wage Base and 4% for covered pay in excess of such wage base; effective July 1, 2003, the percentage became 4% for all subsequent covered pay. For this purpose, covered pay includes base pay and certain annual incentive bonuses payable during the year. Accrued benefits earn monthly interest based on the average interest rate for five-year U.S. treasury securities. Employees vest in the Plan on completion of five years of service. Vested employees may receive their benefit under the Cash Balance Plan as a lump sum or as a monthly payment when they leave Owens Corning. For employees who were at least age 40 with 10 years of service as of December 31, 1995 ("Grandfathered Employees"), including Messrs. Brown and Kiemle, the credit percentages applied to covered pay are increased pursuant to a formula based on age and years of service on such date. In addition, Grandfathered Employees are entitled to receive the greater of their benefit under the Prior Plan frozen as of December 31, 2000, or under the Cash Balance Plan (in each case including the ESBP). The estimated annual annuity amounts payable under the Cash Balance Plan (including the ESBP) to the Named Executive Officers at age 65 are: Mr. Brown, $344,391; Mr. Thaman, $320,027; Mr. Kiemle, $183,433; Mr. Dana, $87,214; and Mr. High, $44,030. These estimated amounts assume continued employment and current levels of base salary, plus target annual incentive, through age 65, and are based on estimated interest rates. Supplemental Executive Retirement Plan - Owens Corning maintains a Supplemental Executive Retirement Plan ("SERP") covering certain employees, including Mr. High, who join Owens Corning in mid-career. The SERP provides for a lump sum payment following termination of employment equal to a multiple of the covered employee's Cash Balance Plan balance minus an offset equal to the present value of retirement benefits attributable to prior employment. The applicable multiplier for each covered employee ranges from 0.5 to 4.0 (determined by the covered employee's age when first employed by Owens Corning) and is 2.4 in the case of Mr. High. The estimated annual annuity amount payable to Mr. High to satisfy the lump sum obligation under this plan at age 65, under the assumptions described in the preceding paragraph, is $105,672, less the annualized offset due to prior employment. Other Arrangements - Owens Corning has agreed to provide Mr. Dana a supplemental pension benefit, under Owens Corning's pension plan formula in existence on his employment date, determined as if he had earned 1 1/2 years of service for each year worked, provided that he remains an Owens Corning employee for no less than ten years following his November 15, 1995 employment date. The estimated supplemental annual annuity amount payable to Mr. Dana at age 65 to satisfy this benefit, assuming continued employment and current levels of covered pay, is $211,606. -58- ITEM 11. EXECUTIVE COMPENSATION (continued) In 1992, Owens Corning established a Pension Preservation Trust for amounts payable under the ESBP as well as under the individual pension arrangements described above. The Compensation Committee determines the participants in and any amounts to be paid with respect to the Pension Preservation Trust, which may include a portion of benefits earned under the ESBP and the pension agreements described above. Amounts paid into the Trust and income from the Trust reduce the pension otherwise payable at retirement. During 2004, no payments were made to the Trust. Employment, Severance, and Certain Other Agreements - --------------------------------------------------- Owens Corning maintains a Corporate Incentive Plan under which participating employees, including each of the Named Executive Officers, are eligible to receive annual cash incentive awards based on their individual performance and on corporate performance against annual performance goals set by the Compensation Committee. For the 2004 and 2005 annual performance periods, the funding measures set by the Compensation Committee are based on "income from operations" (weighted at 75%) and "cash flow from operations" (weighted at 25%). Cash awards paid to the Named Executive Officers under the Corporate Incentive Plan for the 2004 performance period are reflected in the Summary Compensation Table above. Effective beginning with calendar year 2004, Owens Corning maintains a Key Employee Retention Incentive Plan ("KERP") to provide an incentive to designated key employees, including each of the Named Executive Officers, to remain in the employ of the Company through the date of the Company's emergence from Chapter 11. Under the KERP, each eligible employee is entitled to a cash payment equal to (1) a specified percentage of his or her annual base salary if such employee remains employed by the Company through the end of the applicable calendar year or (2) a prorated portion of such specified percentage in the event of the Company's emergence from Chapter 11 proceedings (or such employee's termination of employment due to death, disability, or termination other than for cause) prior to the end of the applicable calendar year. As of the current time, the Bankruptcy Court has approved the KERP for calendar years 2004 and 2005. Cash awards paid to the Named Executive Officers under the KERP for calendar year 2004 are reflected in the Summary Compensation Table above. Owens Corning has entered into severance arrangements with each of the Named Executive Officers. These agreements generally provide for the payment of an amount equal to two times base salary plus annual incentive bonuses (based on an average of the three previous years' annual incentive payments or the average of the three previous years' annual incentive targets, whichever is greater) plus continuation of insurance benefits for a period of up to two years and, in the case of Messrs. Brown, Thaman, and Kiemle, a payment equal to the additional lump sum pension benefit that would have accrued had such individuals been three years older, with three additional years of service, at the time of employment termination and, in the case of Mr. Dana, a payment equal to the greater of (1) the additional lump sum pension benefit so calculated and (2) Mr. Dana's supplemental pension arrangement described above. Effective February 16, 2005, the base salaries of the Named Executive Officers are: Mr. Brown, $750,000; Mr. Thaman, $650,000; Mr. Kiemle, $325,000; Mr. Dana, $350,000; and Mr. High, $325,000. Directors' Compensation - ----------------------- Retainer and Meeting Fees - Owens Corning compensates each director who is not an Owens Corning employee pursuant to a standard annual retainer/meeting fee arrangement. Effective July 1, 2004, such arrangement provides each non-employee director an annual retainer of $100,000, a fee of $1,500 for attendance at each meeting of a Board Committee of which such director is a member, no fees for attendance at meetings of the Board of Directors, and a fee of $1,500 for each day's attendance at other functions in which directors are requested to participate. In addition, Chairmen of Board Committees -59- ITEM 11. EXECUTIVE COMPENSATION (continued) receive an additional annual retainer of $7,500. Prior to July 1, 2004, Owens Corning paid each director who was not an Owens Corning employee an annual retainer of $35,000 and a fee of $1,200 for (a) attendance at one or more meetings of the Board of Directors on the same day, (b) attendance at one or more meetings of each Committee of the Board of Directors on the same day, and (c) each day's attendance at other functions in which directors were requested to participate. In addition, Committee Chairmen received an additional retainer of $4,000 each year. Prior to December 2000, a director could elect to defer all or a portion of his or her annual retainer and meeting fees under the Directors' Deferred Compensation Plan, in which case his or her account was credited with the number of shares of common stock that such deferred compensation could have purchased on the date of payment. The account was also credited with the number of shares that dividends on previously credited shares could have purchased on dividend payment dates. The Deferred Compensation Plan provides that account balances are payable in cash based on the value of the account, which is determined by the then fair market value of Owens Corning common stock, at the time the participant ceases to be a director. Under the terms of the Deferred Compensation Plan, the claims of directors to the cash value of such deferred shares is effectively equivalent to a claim as a general unsecured creditor of Owens Corning. Although no assurance can be given as to the value, if any, that would be attributed to such a claim under any plan or plans of reorganization ultimately confirmed in the Chapter 11 proceedings, any value ascribed to such a claim may be greater than the value of the number of shares of Owens Corning common stock the receipt of which was deferred if, as anticipated, the outstanding Owens Corning common stock is cancelled as part of the implementation of such plan or plans of reorganization. Stock Plan for Directors - Owens Corning has a pre-petition stockholder approved Stock Plan for Directors, applicable to each director who is not an Owens Corning employee. The plan provides for two types of grants to each eligible director: (1) a one-time non-recurring grant of options to each new outside director to acquire 10,000 shares of common stock at a per share exercise price of 100 percent of the value of a share of common stock on the date of grant, and (2) an annual grant of 500 shares of common stock on the fourth Friday in April. Initial option grants become exercisable in equal installments over five years from date of grant, subject to acceleration in certain events, and generally expire ten years from date of grant. No grant may be made under the plan after August 20, 2007, and a director may not receive an annual grant of common stock in the same calendar year he or she receives an initial option grant. A director entitled to receive an annual grant may elect to defer receipt of the common stock until he or she leaves the Board of Directors. Pursuant to action of the Board of Directors, additional option grants and annual grants under the Plan were suspended effective April 1, 2002, pending further action by the Board. No initial option grants or annual grants were made under the Plan during 2004. Indemnity Agreements - Owens Corning has entered into an indemnity agreement with each member of the Board of Directors which provides that, if the director becomes involved in a claim (as defined in the agreement) by reason of an indemnifiable event (as defined in the agreement), Owens Corning will indemnify the director to the fullest extent authorized by Owens Corning's by-laws, notwithstanding any subsequent amendment, repeal or modification of the by-laws, against any and all expenses, judgments, fines, penalties and amounts paid in settlement of the claim. The indemnity agreement also provides that, in the event of a potential change of control (as defined in the agreement), the director is entitled to require the creation of a trust for his or her benefit, the assets of which would be subject to the claims of Owens Corning's general creditors, and the funding of such trust from time to time in amounts sufficient to satisfy Owens Corning's indemnification obligations reasonably anticipated at the time of the funding request. -60- ITEM 11. EXECUTIVE COMPENSATION (continued) Charitable Award Program - To recognize the interest of Owens Corning and its directors in supporting worthy educational institutions and other charitable organizations, Owens Corning permits each director who joined the Board prior to December 31, 2001 (subject to certain vesting requirements) to nominate up to two organizations to share a contribution of $1 million to be made in ten annual installments after the death of the director. Owens Corning expects to fully fund its contributions (as well as insurance premiums) from the proceeds of life insurance policies that it maintains on directors. Directors will receive no financial benefit from this program, since the charitable deduction and insurance proceeds accrue solely to Owens Corning. Compensation Committee Interlocks and Insider Participation The Compensation Committee presently consists of Landon Hilliard (Chairman), Gaston Caperton, Ann Iverson, and W. Ann Reynolds. No other persons served on the Compensation Committee during 2004 except Furman C. Moseley, Jr., a former director. Mr. Hilliard is a partner of Brown Brothers Harriman & Co. ("BBH"), a private banking firm. BBH acts as one of the investment managers for the Fibreboard Settlement Trust, which holds certain assets that are available to fund asbestos-related liabilities of Fibreboard Corporation, a subsidiary of Owens Corning. During 2004, BBH was paid fees of approximately $758,000 from the Trust for these services. In addition, BBH serves as the custodian and investment advisor of certain escrow accounts funded by the Company's excess insurance carriers (see Note 19, Item C, to the Consolidated Financial Statements). During 2004, BBH earned fees of approximately $86,000 for these services.
